RWS434A SAW Based Receiver

---------------------------------------------------------------------------------------------

These modules operate on 433.92, 418 or 315 Mhz., same as the standard RWS 434 & TWS 434 modules but they have made significant changes in the size of the unit. They are SAW based and offer about 100 meters range in Line-of-Sight operating form 2-12 volts. The new version has a data rate of 4.8KB/s, over double the speed of the previous version and still provides 16DBm of output power off under 20mA of current. The module uses ASK as the form of modulation and has both digital and analogue outputs.

The size and simplicity of these units make them a professional and economical solution for many wireless applications. Is full compatible with the older version of the RWS433 for the advantage of people with existing units however we would recommend their use with the New RWS433A.  Freq is 433.92 MHz


The unit price is only US$4.70 e.a. for 1000 pieces.
